Most buyers expect hotel rates to increase in 2012, and few expect their hotel volume to drop next year, according to an AirPlus International survey of 101 corporate travel buyers in Europe and North America . A little more than a third of respondents said they plan to maintain relationships with their preferred hotel suppliers even if that meant bearing rate increases, while about a quarter said they would be willing to change suppliers if it resulted in lower rates. Only about 7 percent said they planned to explore dynamic pricing models.
